mass knuckle

Moose knuckle or camel toe, but in the back. As if someone was wearing spandex and hiding two bagels between their legs just Nader the grundle.

“Oh man, this woman flossed a wicked mass knuckle yesterday at the swap meet.”

Ass Knuckles

When a woman (sometimes a man) wears short shorts and the bottom part of her buttcheeks are showing. Mainly the part where the cheek meets the leg.

"Wow check out melissa in those short shorts you can totally see her ass knuckles!"

Knuckle buster

While in spoon position with your partner, you put your pinky in the Booty hole, ring and middle fingers in the vagina, and use your pointer finger to stimulate the clitoris.

Whether my wife is being naughty or nice, I always end the night with a knuckle buster.

Knuckles the echidna

& knuckles & knuckles & knuckles & knuckles.
anyway, Knuckles is a red echidna and is the protector of the Master emerald. the master emerald holds all the power of all the other 7 emeralds. Knuckles is what people call a "badass". he doesn't care what people have to say and used to not get along with sonic because eggman tricked him into thinking sonic took the master emerald when really eggman did. knuckles has appeared in most of the sonic games since " Sonic the hedgehog 3 & knuckles". and he is also getting a tv show soon based off his role in the 2nd (actually 3rd cause of the ova) Sonic movie, which went to theaters in april 8 2022!

sonic: hey tails where is Knuckles?
miles "tails" prower: oh idk, he's either with rouge the bat or protecting the emeralds as usual.

knuckles: I'm over here Knuckleheads.
and I'm named knuckles the echidna.
